GU-826 – Process Safety Letter of Assurance Guideline – PDO

The LoA was introduced to give assurance that we are managing our major process safety risks and also an opportunity to escalate PSM issues to a higher level. It is also providing a common platform for all Directorates and force shared learning to improve process safety performance.

This guide is intended to aid in understanding the rationale and completing the KPIs (metrics), self-assessment, and learning from incidents sections of LoA. The KPIs and processes have been adopted/selected based on industry best practices (OpExcellence, CCPS, and API RP754) customized to PDO’s needs. The LoA identifies opportunities for improving the management and control of process risk, and so is a key driver for continuous improvement.

Asset Director shall submit AI- PSM Letter of Assurance (LoA) every year by mid-February to TD in accordance with the guidelines stated here and the LoA document itself. The LoA is an annual declaration from the Director, with or without qualifications, that the current implementation status of the Process Safety management system meets the established standards, Asset performance and condition is within acceptable limits, and the requirements of LoA have been met.
